WM4
Magnetometer

The WM4 is a much-anticipated and welcome addition to the family of magnetometers from RHINO Detection. WM4 Magnetometer represents the best in innovation at work for the water/sewer industry, surveying industry and military. That’s because the WM4 reflects many of the items on our customers’ technological wish lists. The WM4 is 40″ to meet surveyors’ personal preference, providing an ergonomic, lightweight, rugged, one-handed operation option to traditional magnetic locators. The WM4 offers unparalleled durability, as all components are housed inside the aircraft-grade aluminum monotube units. But don’t let its looks fool you. The WM4 is the only magnetic locator in the world that is 100 percent waterproof, IP68 certified up to 250 feet – a first for the industry – so it can be used in difficult weather and submerged under water. Plus, its auto-zero feature allows the user to “cancel” ambient magnetics or magnetic gradient in the soil or water. And it’s digitally tuned, so it offers unparalleled accuracy in detecting ferromagnetic objects.
